Seems to be related to https://github.com/angular/angular/pull/35846/ Actually we found a call to the function:

function ɵɵNgOnChangesFeature(definition) {
    if (definition.type.prototype.ngOnChanges) {
        definition.setInput = ngOnChangesSetInput;
        ((/** @type {?} */ (definition))).onChanges = wrapOnChanges();
    }
}

without any param here (see last property features ):

NgComponentOutlet.ɵdir = ɵngcc0.ɵɵdefineDirective({ type: NgComponentOutlet, selectors: [["", "ngComponentOutlet", ""]], inputs: { ngComponentOutlet: "ngComponentOutlet", ngComponentOutletInjector: "ngComponentOutletInjector", ngComponentOutletContent: "ngComponentOutletContent", ngComponentOutletNgModuleFactory: "ngComponentOutletNgModuleFactory" }, features: [ɵngcc0.ɵɵNgOnChangesFeature()] });

@sahlifiras26 you are simply using a library not well packed or you have to build correctly yours. @ericmartinezr would you be so kind as to help us with a little advice?
